Peace Lily, specifically the Variegated Peace Lily (cultivar 'Domino' or similar)
Kingdom: Plantae, Division: Tracheophyta, Class: Liliopsida, Order: Alismatales, Family: Araceae, Genus: Spathiphyllum, Species: Spathiphyllum wallisii · Araceae (Arum or Aroid family) · Simple, Evergreen perrenial foliage

Species
Spathiphyllum wallisii (Likely 'Domino' or 'Jessica' cultivar)
Leaf Type
Simple, Evergreen perrenial foliage
Family
Araceae (Arum or Aroid family)
Shape
Lanceolate to narrowly ovate with an acuminate (pointed) tip
Size
Approximately 5-7 inches in length; this is standard for indoor cultivars which range from 4 to 12 inches.
Margin
Entire (smooth) but often appears slightly undulate or wavy
Arrangement
Basal rosette (leaves emerge from the center of the plant on long petioles)
Rarity
Common as a houseplant; the variegated 'Domino' variety is slightly less common than the standard dark green version but widely available.
Color & Pattern
Strongly variegated. Features a creamy-white to light yellow border with a splashed, irregular dark green center. Some intermediate light green 'ghosting' is visible where the pigment layers overlap.
Venation Pattern
Pinnate-parallel; the secondary veins run parallel to each other from the midrib toward the margin in a distinct 'ribbed' appearance.
Texture & Surface
Smooth (glabrous) and slightly glossy to matte. The surface is somewhat puckered or rugose, which is a characteristic of variegated Spathiphyllum cultivars.
Description
An elegant herbaceous perennial known for its striking white spathe (flower) and lush foliage. The variegated form adds a marbled texture to the room. It grows in clumps of upright leaves on slender stalks.
Key Features
Lance-shaped variegated leaves, prominent parallel venation, and the characteristic white 'pucker' or crinkle often found in the white sections of the leaf.
Habitat
Originally tropical rainforest floors; as a houseplant, it prefers high humidity, indirect light, and consistently moist, well-draining soil.
Geographic Range
Native to tropical regions of the Americas (Colombia and Venezuela), but this variegated cultivar is a product of horticultural selection found worldwide.
Condition Notes
Excellent health. No signs of brown tips (indicating good humidity) or yellowing (indicating proper watering). The variegation is sharp and distinct.
Interesting Facts
Spathiphyllum was famously included in the NASA Clean Air Study for its ability to remove common indoor toxins like benzene and formaldehyde from the air.
Medicinal & Uses
Primarily used as an ornamental indoor plant. It has no significant medicinal uses and is prized strictly for its aesthetic and air-purifying qualities.
Ecological Role
In its native habitat, it provides ground cover in the understory and is pollinated by bees and beetles attracted to its spadix.
Similar Species
Aglaonema (Chinese Evergreen), which has thicker stems and different leaf attachment, or Dieffenbachia, which has much thicker, woodier stalks.
Foraging Tips
Do not forage in the wild unless in the neotropics. In the home, look for drooping leaves as a 'tell' that the plant needs immediate watering.
Toxicity Warning
Moderately Toxic. Contains calcium oxalate crystals which cause immediate mouth irritation, swelling, and drooling if ingested by humans or pets.
